Molecular and Morphological Analyses Reveal Phylogenetic Relationships of Stingrays Focusing on the Family Dasyatidae (Myliobatiformes) [PDF]
PLoS ONE, 2015 Elucidating the phylogenetic relationships of the current but problematic Dasyatidae (Order Myliobatiformes) was the first priority of the current study. Here, we studied three molecular gene markers of 43 species (COI gene), 33 species (ND2 gene) and 34

The complete mitochondrial genome of pitted stingray Bathytoshia brevicaudata (Myliobatiformes: Dasyatoidea) [PDF]
Mitochondrial DNA. Part B. Resources, 2020 The complete mitochondrial genome of pitted stingray, Bathytoshia brevicaudata (Myliobatiformes: Dasyatoidea) was investigated by next-generation sequencing. The analyzed mitochondrial genome was 17,640 nucleotides in length and had 59.2% for AT contents.

Aerial Imagery Reveals Abnormal Stingray, Taeniura lymma (Myliobatiformes: Dasyatidae), in the Central Red Sea [PDF]
Ecology and EvolutionWhile morphological abnormalities have been widely reported in batomorphs, ontogenetic deformities of the posterior pectoral fin are rare. In this paper, we present a bluespotted ribbontail ray, Taeniura lymma (Forsskål, 1775), with symmetrically ...

First record of Aetomylaeus asperrimus Gilbert, 1898, Roughskin Eagle Ray (Myliobatiformes, Myliobatidae), from El Salvador: additional data from the Eastern Tropical Pacific [PDF]
Check ListIn 2024, two females of Aetomylaeus asperrimus Gilbert, 1989 (Myliobatiformes, Myliobatidae) were caught while fishing using an artisanal longline in El Salvador. The rays were identified by their rhomboid disc and unique dorsal pattern.

Branching patterns of the afferent branchial arteries and their phylogenetic significance in rays (Batoidea) [PDF]
Scientific Reports, 2021 Rays of the superorder Batoidea comprise the most diverse group of chondrichthyans in terms of valid species and morphological disparity. Up to the present little agreement is observed in studies based on morphological and molecular data focused on ...
